2027 New Fire ceremony[edit]

We could add the 2027 New Fire ceremony. Here are some quotes from Wikipedia:
It was believed that during these days the world was in grave danger because of the instability inherent in the shift from one cycle to another. It was feared that female stellar deities, the Tzitzimime, would descend and devour the earth.
For that reason, every 52 years, when the beginning of the calendars (Civil and Religious) coincided, the sacerdotal class performed the New Fire ceremony, to prevent the Sun’s death, as they thought, would cause total darkness of the universe, allowing the sprouting of tsitsimeme, entities that ate human beings.
From the Tzitzimitl article: It was said that if at the end of a 52 year calendar round, that if they could not start a bow fire in the empty chest cavity of a sacrificed human, that the fifth sun would end, and tzitzimimes would descend to devour the last of men.
Here are books talking about the 2027 occurrence:

500,000 years[edit]

Saying that an asteroid of 1 km in diameter should hit Earth 500,000 years from now is misleading. While admittedly it was hard to find a source that accurately depicted how big of a crater a 1 km asteroid would make (most seemed to exaggerate by a lot) I was able to use an online calculator and calculated it with a density of 2,000 kg/m3 and a 45° impact angle to get a diameter of 9-10 km depending on the ground it landed on.[1] The youngest discovered crater with a diameter greater than 9 km is Zhamanshin crater in Kazakhstan which is aged at 900,000 ± 100,000 years. Going forward 2 cycles, and assuming the intermediate asteroid landed in the ocean or simply hasn't been discovered, that would put the next impact sometime within the next 200,000 years, not 500,000.

You're probably right. But if you had to figure that out yourself with a calculator and it's not actually in a source, that's original research and it cannot be added to the article. Damien Linnane (talk) 09:54, 3 November 2019 (UTC)

Inclusion of Eric Christian Hansen entry?[edit]

Why is this section on this list? Eric Christian Hansen does not seem notable enough, and the entry's grammar is all wrong too, although that shouldn't warrant removal on its own 208.97.122.194 (talk) 21:01, 3 December 2019 (UTC)

It was added very recently. I've just removed it as it definitely isn't notable enough. Damien Linnane (talk) 21:16, 3 December 2019 (UTC)
